Questions
The ends of a stretched wire of length L are fixed at x = 0 and x = L. In one experiment, the displacement of the wire is and energy is E1, and in another experiment its displacement is and energy is E2. Then
detailed solution
Correct option is C
Energy (E) ∝ (Amplitude)2 (Frequency)2 Amplitude is same in both the cases, but frequency 2 ω in the second case is two times the frequency (ω) in the first case. Hence E2=4E1.Talk to our academic expert!
